Answer 1

Use Convert.ToInt32:

Convert.ToInt32(theString, 16)

It uses this overload:

public static int ToInt32(string value, int fromBase)

Note that you will get FormatException because of the g in the string:

FormatException
value contains a character that is not a valid digit in the base specified by fromBase. The exception message indicates that there are no digits to convert if the first character in value is invalid; otherwise, the message indicates that value contains invalid trailing characters.

You’re not getting error in javascript as js tends to "forgive" too much errors, this one one of those examples.
